Thanks for the note.

I was aware that the factory interval is 100K (or it it 105K?).
However, it is pretty common knowledge among mechanics and owners
that, although the timing belt itself will easily last that long, many
of the components surrounding it-- like the water pump and belt
tensioners-- often fail much earlier. Failure of any of these
components will take out the belt and the top-end of the motor...

My water pump bearings are already starting to make sick gerbil noises
when cold, so the handwriting is on the wall...
